This invention relates to painting devices and more particularly to striping 1nstruments.

An object of the invention is to prov de an instrument for painting a wavy stripe pf uniform width and wavy throughout 1ts length.

Another object of the invention is to. provide an instrument for painting a we. stripe of uniform width and wave concomitantly with the painting of a strips or stripes arranged adjacent thereto.

A further object of the invention is to provide an instrument for painting a wavy stripe in which a predetermined quantity, of paintis metered or fed through anozzle proportionately to the rate of movement of the instrument over the surface under treatment. v vA further, object of the invention is to provide an instrument for paintlng a wavy stripe by im arting to a nozzle through which paint is fed an oscillatory movement as the paint is deposited on a surface under treatment, the palnt being fed through the nozzle in proportion to the rate of movement of the instrument over the surface.

A still further object of the invention is to provide an instrument for painting a wavy stripe wherein paint is metered or fed through a nozzle by a gear pump, and the nozzle caused to oscillate in a horizontal plane by a cam on a rotatable guide so that the rate of movement of the guide determines the rate of movement of the nozzle.

A still further object of the invention is to provide an instrument for painting stripes comprising in combination with means for painting parallel stripes, a pump mechanism for metering or feedlng palnt to an oscillatory nozzle, the operation of the pump and movement of. the nozzle being controlled or governed by a rotatable guide member having a plurality of cams thereon arranged within a circle so that upon rotation of the guide member as the instrument is moved over the surface under treatment the pump is operated to feed paint through the nozzle proportionate to the rate of movement of the instrument over the surface under treatment and the -nozzle is caused to oscillate in a horizontal plane by the cams carried on the rotatable guide, the nozzle being pressed in engagement with thecams so that the wave will be uniform throughout the length of the stripe.

With these and other objects in view which may be incident to my improvements, the invention consists in the parts'and combinations to be hereinafter setforth and claimed, with the understanding that the several necessary elements comprising my invention may be varied in construction, proportion and arrangement, without departing from the spirit or scope of the appended claims.

In order to make my invention more clearly understood I have shown in the accompanying drawings means for carrying the same into practical efi'ect without limit- 1ng the improvements in their useful a plication to the particular construction, w ich for the purpose of explanation, has been made the subject of illustration.

Other objects of the invention will appear in the following description taken in connection with the drawings which form a part of this specification, and in which:

Fig. 1 is atop plan view with the containers removed and the distributing shaft in section;

Fig. 2 is a side elevation partly broken away, and partly in dotted lines;

Fig. 3 is an end elevation with the containers broken away, and" Fig. 4 is a fragmentary view illustrating the pump mechanism in dotted lines.

Referring to the drawings for more specific details of the invention, 10 represents a body portion which is substantially rectangular in general contour. Positioned on one side of the body portion is a plate 11. This plate has positioned therein-a threegear pump comprising three overlapping transverse bores 12, 13 and 14 in which are arranged three intermeshing gears 15, 16 and 17 and on the opposite side of the bod portion is a plate 18 having positioned t erein a two-gear pump comprising overlapping transverse bores 19 and 20 in which are arranged intermeshing gears 21 and 22, the gear 21 being in axial alignment with the gear 16. .The plate 11 is covered by a face plate 23 and the plate 18 is covered by a face plate 24, the plates 11, 18, 23 and 24 being secured to the body portion by means of suitable screws 25 passing transversely through the plates and body portion.

A shaft 26 extends transversely through the body portion and has keyed thereon the gears 16 and 21. This shaft has on one end a roller 28 secured in position by a pin 29 and on the other end a flanged roller 30 keyed on the shaft by a pin 31. The roller 30 is provided with beveled flanges 32, one of which has arranged thereon within a circle, the center of which is in the axis of the roller, a cam 33 having a plurality of lobes, the object of which will hereinafter appear. Supported by the body portion 10 is a shaft 34 having mounted thereon for rotation a roller 35. The shaft 34 is provided with a reduced portion 36 which extends transversely through the body portion and plates and receives a nut 37 by which the shaft is rigidly secured in position.

Positioned intermediate the shaft 26 and the shaft 34 is a distributing shaft 38. This shaft extends normally from the body of the instrument parallel to the shafts 26 and 34 and is provided with circumferential slots 39 and 40 and an axial bore 41. Positioned in the top of the body portion is a container 42 communicating with an intake 43 of the three-gear pump, the corresponding outlet of which is indicated at 44. The outlet 44 communicates with a passage 45 which in turn communicates with the axial bore 41. The container 42 also communicates with an intake 46, the corresponding outlet of which is indicated at 47. The outlet 47 communicates with a passage 48 which in turn communicates with the slot or groove 40 in the circumference of the shaft 38.

Mounted in the top of the body portion is a second container 49 communicating with a passage '50 which leads to the intake 51 of the two-gear pump, the outlet of which is indicated at 52. The outlet 52 communicates wit-h a passage 53 leading to and communicating with the slot 39 in the circumference of the shaft 38.

Positioned on the shaft 38 is a sleeve 54 having formed thereon a nozzle 55 provided with a passage 56 communicating with the groove 40 in the circumferenceof the shaft 38. The sleeve 54 is provided with a cup 57 in which is positioned a ball 58 having formed thereon a nozzle 59 provided with a passage 60 communicating with a diametrical bore 61 extending through the ball normal to the passage 60. The bore 61 is substantially oval as indicated at 62 so that when fitted on the shaft 38 the nozzle 59 may be oscillated in a horizontal plane and spring 67 retains in position the sleeves 54 and 63 and the ball 58 so that the nozzles carried by these members are maintained in their proper relation to one another, and the nozzles are pressed to engage the surface under treatment by springs 7 O secured thereto in any suitable manner and suitably supported in a bracket or in 71 extending normal from the body por ion.

The nozzle 59 is provided with an arm 72 which engages the face of the cam 33 on the guide roller and the arm is held or urged in engagement with the cam by a coil spring 73 positioned between the nozzle 59 and the nozzle 65, the latter nozzle being fixed against lateral movement.
